vertical direction. 2 Hanging material hit people. 1 It violated safety regulation for operation that throwing materials. 3 Vehicle hurt people. 2 The electrician doesn’t do the power transmission according to the prescribed procedure. 3 The safe voltage is not used in moist place. 2 The equipment is not be powered off when it is out of use. 2 The electric welding is operated by non-professional welder. 4 The welding line and loop zero line is not in place completely. 2 The equipment was not out of service according to regulations when it was found that there is something wrong with it. 2 The hand-held electric tools are used before resistance test. 1 Electro-gas welding is operated illegally, there is hole which is not sealed up under the working place vertically. 3 Lengthen power line or change plug illegally with hand-held electric tools. 2 3 The personnel safety risk factor analysis of electromechanical installation project in construction phase 3.1 Questionnaire design and data
Therefore the scale has higher reliability. 3.2 The factor analysis Factor analysis is the promotion and development of the principal component analysis, and it also belongs to the multivariate analysis process of dimension reduction.

However, when the admixture is over 20%, the reduction is not that obvious.
But there are still disputes about the influence of one-day silica fume on the autogenous shrinkage of concrete, which remains to be further observed through tests and theoretical analysis, aiming to draw an appropriate and accurate conclusion. 2 Relationship between early-age autogenous shrinkage and the amount of mineral admixtures Regression analysis has been conducted for the current domestic test data[2, 4, 8, 10, 12], and it has been discovered that there is a remarkable linear dependence between the early-age autogenous shrinkage and the fly ash, ground slag and silica fume admixtures, which can be described with the following formula

A study of data dedicated to the application of natural zeolites and published after 2003 was carried out in our project [7].
Fig. 3.Block diagram of technical process of waste waters purification from ammonium ions Block diagram of two stage process, consisting of combination – absorption of the basic mass of ammonium ion (concentration reductionfrom 2000 mg/l to 20 mg/l) by treatment with powder NZ in the stirred reactor and dynamic advanced treatment (concentration reduction from 20 mg/l to 2 mg/l or less) is shown in fig. 3.

Over the years, various types of Fe3O4 nanostructures, including spheres [11], wires [12], fractals [13], hollow structures [14], and nanosheets [15] have been prepared by different synthesis methods, such as reduction of hematite [16], co-precipitation route [17], microwave plasma synthesis [18], microemulsion methods [19], ultrasound irradiation [20], hydrothermal process [21], and so on.
The data is consistent with the values in the literature [29], which further proves the composition of the magnetic Fe3O4.

The geologic data reference the report of geotechnical investigation on west fourth ring Fuxing road.

Table 4 displays the crystallographic data used for phase determination from the ICDD-database.
In the future the focus has to be on the reduction of carbide formation during thermal processing due to the adjustment of the sintering atmosphere.

One of the most outstanding features of the alloy is its cold formability, such as cold rolling reductions in excess of 90% after solution treated[3].
The data in Table 1 suggests that the present operation parameters carried out in the TIG process, together with the AA or ST+AA treatment, are satisfactory to enhance the industrial application of the Ti-15-3 alloy.

To data, FESEM and TEM analysis are the most used and direct methods to characterize the percentage of the exposed {001} facets.
However, as the percentage of the exposed {001} facets further increased, the reduction of the diffraction intensity may be ascribed to the not very perfect crystal structure.

Because of the reduction in force transfer between fibers and the resin, the mechanical properties of the FRP reinforcements would be reduced.
Verification of the Model The numerical model prepared using ANSYS Workbench is verified from the data of full-scale fire tests conducted on six RC beams strengthened with CFRP sheets, which were protected with different insulation materials conducted by Firmo et al. [21].

Introduction The decisive tendency of the heat insulation materials production is the density decrease, the improvement of the heat engineering indicators, the energy intensity reduction.
